Provided is a heater of a prismatic valve capable of facilitating installation thereof while securing adhesion of the heater to a main body of the prismatic valve. In a prismatic valve (10) having a prismatic main body (11) and a first flow path (13) of fluid formed on a side surface (11a) of the main body (11), a heater (20) is installed on the side surface of the main body (11) and includes a strip-shaped heater unit (21) having a length along the entire side surfaces of the main body (11) except for the side surface (11a); insulating members (31b-31d) installed on the positions corresponding to the side surfaces of the main body (11) of the heater unit (21), respectively; strip-shaped winding sections (41, 45) installed at predetermined places of both ends of the insulating member (31d) in a width direction of the heater unit (21), and configured to wind, at least one turn, around the side surface of the main body (11) from the outside of the insulating member in a state whereby the heater unit (21) is wound while the insulating member is disposed outside the side surface of the main body (11); and surface fasteners (51, 55) installed on the winding sections (41, 45) and hooked to fix the winding sections, respectively. |
